My daughter and I have a "game" at the Thrift Store that we started when we arrived in 08/11-- we see a roundish, usually either red or white, Cooker Thing, and before we open it, we have to guess what the inside "grid layout" will be.

How hard is it to roll the dog biscuit batter and cut it with a bone-shaped cutter? I have a photo of my daughter at 3-years-old doing just that. For that matter, the dog really doesn't care if the treat is shaped like a bone, a disk, or a blob as long as it's food.
